【摘要】：針對基于Reich模型的平行航路側(cè)向間隔碰撞風(fēng)險(xiǎn)評估過程中,機(jī)型尺寸與巡航速度對評估精度產(chǎn)生影響這一問題,引入改進(jìn)后的橢柱型模型對基于甚高頻全向信標(biāo)(VOR)導(dǎo)航臺的平行航路下飛行器側(cè)向碰撞風(fēng)險(xiǎn)進(jìn)行仿真建模分析。首先確定影響空域安全性評估的各參數(shù)間的關(guān)系,再根據(jù)飛機(jī)側(cè)向偏航距離的分布規(guī)律,應(yīng)用新模型分析得出碰撞風(fēng)險(xiǎn)的發(fā)生概率。采用實(shí)際飛行數(shù)據(jù)進(jìn)行仿真實(shí)驗(yàn),在給定航路距離、機(jī)身相對距離、偏航距離的情況下,對VOR導(dǎo)航下兩機(jī)側(cè)向碰撞率分析得出:當(dāng)機(jī)身長度提高57.1%時(shí),碰撞風(fēng)險(xiǎn)提高了47.7%;而當(dāng)巡航速度提高4.8%時(shí),碰撞風(fēng)險(xiǎn)增加了7.6%。實(shí)驗(yàn)證明利用該方法能夠分析航空器尺寸及航行速度對航路碰撞風(fēng)險(xiǎn)的具體影響,進(jìn)而可在滿足安全目標(biāo)水平條件下縮小最小安全間距,提高空域利用率。
[Abstract]:In the process of side collision risk assessment based on Reich model, the model size and cruise speed have an impact on the evaluation accuracy. An improved ellipsoid model is introduced to simulate and analyze the lateral collision risk of aircraft under parallel routes based on VHF omnidirectional beacon (VHF) navigation station. First, the relationship between the parameters affecting the airspace safety assessment is determined, and then the probability of collision risk is obtained by using the new model analysis according to the distribution of the aircraft lateral yaw distance. Using the actual flight data to carry on the simulation experiment, under the given route distance, the fuselage relative distance, the yaw distance, the analysis of the two aircraft lateral collision rate under the VOR navigation: when the fuselage length increases 57.1%, Collision risk increased 47. 7%, while when cruising speed increased 4. 8%, collision risk increased 7. 6%. The experimental results show that this method can be used to analyze the impact of aircraft size and navigation speed on the collision risk of air route, thus reducing the minimum safety distance and improving the utilization rate of airspace under the condition of satisfying the level of safety target.
